630 Bleeder resistors

[Geist]

Hi All;
I am checking the power bleeding resistors.. So, far what I seem to have found, is that the upper Round Resistor, seems to be OK.. It is a little low in value, but not serious, Part A, Schematic 1360 ohms, resistor 1338 ohms.. part B, schematic 230 ohms, resistor 224 ohms.. On the part A side it looks a little rough on the outside, part of the outside coating looks like it either was burnt off, or from sitting in a barn, the weather caused it to flake off.. So, should I replace it ??
The lower flat resistor part A Schematic 6750 ohms, resistor 7030 ohms, Part B, Schematic 93 ohms, resistor value varies, won't hold and is in the meg ohms range.. Should I replace Both Parts A and B or just the B side ?? Since it only shows Bad.. I think Part C which shows up in some schematics, this is open, and as a seperate resistor in other schematics.. I will assume it has the seperate resistor, and make the necessary changes, IF needed.. I haven't looked underneath the chassis and tried to find R240, which would be there IF there is no Part C..
THANK YOU Marty
